I have configured the tag history provider of type Internal Historian.
I have tags of datatype double and history configuration as shown in image:
When deadband style is set to Auto, the value change is not being historized immediately after initial value change.
However when deadband style is discrete, the value change is historized immediately.
Please see attached image :
For tagDoubleBuiltIn where style is Auto , the last historized value is 4 whereas current value is 5.
For tagDoubleBuiltin_Discrete the last value in history is 5 which is same as current value.
Why is it that when style is Auto, the previous value is added to the history after next value change ?
This happens with Double / Float tags and not with Integer tag.
Appreciate help in this regard.
